1Preheat the oven to 350. Place a sheet of parchment paper on cookie sheet or baking pan.
2Open the crescent rolls carefully so as not to tear the dough. Do not unroll...you will need to leave it in it's cylindrical shape. Slice the dough into pieces about 1/4 inch thick (as though you're slicing cookie dough).
3Place the slices on a cookie sheet. Now press the center in to make an indentation for the cream cheese filling.
4In a large mixing bowl, mix together the cream cheese, regular sugar, lemon juice, vanilla and sour cream
5Add a dollop of the mixture to the indentation you made in each circle of dough. I find that about a tbsp works well, but you can use as little or as much as you like
6Bake for 15 - 20 minutes. While the danish are baking, you can make a quick royal icing to drizzle over the tops
7Take the danish out of the oven and allow them to cool for 10-15 minutes before icing
8Glaze: Mix together the confectioner's sugar, milk and butter in a small bowl. Use a spoon to drizzle it over the tops of the danish, or you can put it into a small zip-top bag and snip of the corner for an easy "piping bag."
